I soma'citizen oftheUnited States, and resi- T all whom may concern.

Be it l niow-nthat L'WILLIAM- G. ANDER- dent ofAllstoinBoston, county of Suffolk,

Commonwealth of lYIassachusetts, have invented, an Improvement in Rotating Heels,

of which the' following description, in connection with the accompanying drawings, is aspecification, like characters on the drawin'gs representing like parts ineach of the several views. a s This-invention relates, to-heel .pieces of boots and shoes 0f; a type adapted to be readilyapplied to a finished shoe or boot after removing one or more of the outer heel liftsif desired,-though a heel piece formed and applied in accordance with my invention may quite as readily be incorporated in the originalmanufacture of the shoe.

One important object of the invention is to provide. a heel piece adapted to be applied to the heel-of a shoe in a manner-so-as to be shiftable. so as to present constantly' changing wear portions, and providing also a construction whereby a cushioning resilient efl'ect is obtainedfrom air cushions, these .,cushion s being constituted by recesses that l are, adapted tojservealso as suction devices to make a non-slipping tread.

A further object of the invention is to provide animproved heel piece constituting a bottomorwear member mounted and apr equally so that running. down of the heel to either side or at the back is prevented.

plied to the heelof the shoe in a manner permitting. constant shifting of position about an axisof;rotation-whereby all peripheral pqrtionsofgtheheel piece are worn down To. this end I .proyide a heel piece of circular disk for n." andgiof, a suitable thickness togconstitute a wear piece, and provide the same with .a, central countersunk wear washer preferably of,metal through which is passed a pivot member which maybe .a-

A shoe or boot isindicated ,atSwith a usual heel H which may .be. reduced in. height as much as desired by the removal of 3 my improved heel piece. The heel piece is indicated at 10 as a circular.- disk ofsuitable thickness to constitute a wear piece, for example, about three-eighths of aninchand formed preferably of rubber or rubber subs.

stitute, or like non-slipping materiaL' This wear piece disk is preferablyHofa diameter, approximately equal to the width oftheheelj and is fitted in place so that at its rear side:

it forms a continuation of the heeloutline,

11. The central portion of the outeriface of this heel piece is centrally-recessed or coun slightly tapering downward as indicated tersunk as indicatedrat 12:to receivea-washer...

Th s

heel of the shoe.

In accordance with my invention the metallic washer 13 is made some little larger than the normal dimension of the central recess or countersink 12 and said recessis relatively deep, extending most of" the way the outer lifts thereof for the application of 8 1;

through the heel piece leaving'only a rela- 1 tively .flexible central diaphragm portion.

Thus as the metallic washer is forcibly PIBSSGd'lIltO said recess the heel piece is distorted from its normal flat condition, as 868111111 Fig. 3, to a substantially dished form as seen in F 1g. 4, with the convex side pres'ented outward and leaving a substantial space between the central concave portion of the heel piece and the heel of the shoe as indicated at 15 in Fig. 4. Thus as the weight of the wearer comes upon this heel piece it will yield to be pressed up against or relatively close to the heel ofthe shoe in its central portion as indicatedat 15 in Fig. 1,

"thus imparting a substantial degree of resiliency.- Then as the weight or" the wearer is partly or Wholly reincved from the heel, the heel piece tending to spring again outward, creates a suction which is exerted.

upon the central recess-or cup space 12 wherefrom it results that the heel is prevented from slipping, this action being more pronounced on smooth surfaces such as R polished floors or the like where the action of the suction cup r12 will be more propounced, and where of coursefthis-attribute 1s most desirable. In this way it will be understoodthat the central thin'portion of the heel piece through which the screw 14' asses serves ;':as a flexible dia hr'a n imparting resiliency to the heel and also attaming a suction cup efiect to make the heel piece, non-slipping. In use the heel nor less about its central axis, presenting v By the washer 13, a relativelywide, reliablefand permanent bearing hold of the axisscrew- 14: upon the heel piece is obtained, the me'- constantly changing peripheral portions atthevy'sides, and back ofthe heel so that there is no possibility-ofuneven wear or running clown of'the heel at either side or'the back thereoijbut the wear on the heel-piece will] be substantially uniform until it is worn out.

tallio bearing between the washer 13 and the head bf the screw permitting easy turning of. the heel-piece in the angular shifting thereof, without any considerable 'd eleto present constantly provision '1 of the metallic wear;-

mosses terious Wear as would be the case if'the rub ber of the heel piece were directly engaged by the head of the-screw. Thus except for the provision of the wear washer 13, the heel 1 piece would be apt to be torn. ofi 'espe ally after a short amount of wear which would enlarge the hole 'therethrough around the screw. I have found that by-the cooperative action of,the metallic washer 13 with the head of the screw, when a proper clamping pressure is applied by turning up the screw, the frictional hold between the head of the screw and the washer is just-sufficient to provide proper resistance against ,too free turning of the heel piece, while permitting the same to shift gradually enough changing wear portions as described;

I amlaware that the invention may be of, and I therefore desire the present embodiment to be considere'd-- as illustrative and not restrictive, reference being had to the appendedclaims rather than to the fore f going description .to indicate the" scope of the invention.

Having described my invention, what I claim; as new and desire to secure by Letters Patent. is

I -1. A heelpiece-ifor bootsor shoes, comprising a disk shaped resilient wear'memembodied in other specific forms without departing from the essential attributes thereher having a' central recessor countersink,"

a metallic .washer larger than the. normal .diamet'erof said recessand arranged to be pressed thereinto to distort said wear menr'n ber'to a dished form, an'd a pivot'and, securing member engaged. withsaidw'asher and passed through said wear member to'hold' the same toaheel.

2. Aheel piece for-bootsorshoes, comrising a disk shaped wear member of flexi hie rubber having its. central portion formed with a. relatively deep countersinlz leaving a" relatively thin central diaphragm portion, a washer larger fthan the normal dimension of: said countersink. and arranged to be pressed thereinto to disto t said wear -member to ,adished-shape, and a combined pivot and securing member passed centrally through said- 1 wear.
